    (Elsevier, 2021) Schlick, Cary Jo R.; Yuce, Tarik K.; Yang, Anthony D.; McGee, Michael F.; Bentrem, David J.; Bilimoria, Karl Y.; Merkow, Ryan P.; Surgery, School of Medicine
    Background: Guidelines recommend extended chemoprophylaxis for venous thromboembolism in high-risk patients having operations for inflammatory bowel disease. Quantifying patients' risk of venous thromboembolism, however, remains challenging. We sought (1) to identify factors associated with postdischarge venous thromboembolism in patients undergoing colorectal resection for inflammatory bowel disease and (2) to develop a postdischarge venous thromboembolism risk calculator to guide prescribing of extended chemoprophylaxis. Methods: Patients who underwent an operation for inflammatory bowel disease from 2012 to 2018 were identified from the American College of Surgeons National Surgical Quality Improvement Program for colectomy and proctectomy procedure targeted modules. Postdischarge venous thromboembolism included pulmonary embolism or deep vein thrombosis diagnosed after discharge from the index hospitalization. Multivariable logistic regression estimated the association of patient/operative factors with postdischarge venous thromboembolism. A postdischarge venous thromboembolism risk calculator was subsequently constructed. Results: Of 18,990 patients, 199 (1.1%) developed a postdischarge venous thromboembolism within the first 30 postoperative days. Preoperative factors associated with postdischarge venous thromboembolism included body mass index (1.9% with body mass index ≥35 vs 0.8% with body mass index 18.5-24.9; odds ratio 2.34 [95% confidence interval 1.49-3.67]), steroid use (1.3% vs 0.7%; odds ratio 1.91 [95% confidence interval 1.37-2.66]), and ulcerative colitis (1.5% vs 0.8% with Crohn's disease; odds ratio 1.76 [95% confidence interval 1.32-2.34]). Minimally invasive surgery was associated with postdischarge venous thromboembolism (1.2% vs 0.9% with open; odds ratio 1.42 [95% confidence interval 1.05-1.92]), as was anastomotic leak (2.8% vs 1.0%; odds ratio 2.24 [95% confidence interval 1.31-3.83]) and ileus (2.1% vs 0.9%; odds ratio 2.60 [95% confidence interval 1.91-3.54]). The predicted probability of postdischarge venous thromboembolism ranged from 0.2% to 14.3% based on individual risk factors. Conclusion: Preoperative, intraoperative, and postoperative factors are associated with postdischarge venous thromboembolism after an operation for inflammatory bowel disease. A postdischarge venous thromboembolism risk calculator was developed which can be used to tailor extended venous thromboembolism chemoprophylaxis by individual risk.

    Association of Preoperative Smoking with Complications Following Major Gastrointestinal Surgery
    (Elsevier, 2022) Brajcich, Brian C.; Yuce, Tarik K.; Merkow, Ryan P.; Bilimoria, Karl Y.; McGee, Michael F.; Zhan, Tiannan; Odell, David D.; Surgery, School of Medicine
    Background: Understanding modifiable surgical risk factors is essential for preoperative optimization. We evaluated the association between smoking and complications following major gastrointestinal surgery. Methods: Patients who underwent elective colorectal, pancreatic, gastric, or hepatic procedures were identified in the 2017 ACS NSQIP dataset. The primary outcome was 30-day death or serious morbidity (DSM). Secondary outcomes included pulmonary complications, wound complications, and readmission. Multivariable logistic regression was used to evaluate the association between smoking and these outcomes. Results: A total of 46,921 patients were identified, of whom 7,671 (16.3%) were smokers. Smoking was associated with DSM (23.2% vs. 20.4%, OR 1.15 [1.08-1.23]), wound complications (13.0% vs. 10.4%, OR 1.24 [1.14-1.34]), pulmonary complications (4.9% vs 2.9%, OR 1.93 [1.70-2.20]), and unplanned readmission (12.6% vs. 11%, OR 1.14 [95% CI 1.06-1.23]). Conclusions: Smoking is associated with complications following major gastrointestinal surgery. Patients who smoke should be counseled prior to surgery regarding risks.

    What They Are Not Telling Us: Analysis of Nonresponders on a National Survey of Resident Well-Being
    (Wolters Kluwer, 2022-12-12) Cardell, Chelsea F.; Yuce, Tarik K.; Zhan, Tiannan; Eng, Josh S.; Cheung, Elaine O.; Etkin, Caryn D.; Amortegui, Daniela; Jones, Andrew; Buyske, Jo; Bilimoria, Karl Y.; Hu, Yue-Yung; Surgery, School of Medicine
    Objectives: To characterize nonrespondents to a national survey about trainee well-being, examine response patterns to questions of sensitive nature, and assess how nonresponse biases prevalence estimates of mistreatment and well-being. Background: Surgical trainees are at risk for burnout and mistreatment, which are discernible only by self-report. Therefore, prevalence estimates may be biased by nonresponse. Methods: A survey was administered with the 2018 and 2019 American Board of Surgery In-Training Examinations assessing demographics, dissatisfaction with education and career, mistreatment, burnout, thoughts of attrition, and suicidality. Responders in 2019 were characterized as survey "Completers," "Discontinuers" (quit before the end), and "Selective Responders" (selectively answered questions throughout). Multivariable logistic regression assessed associations of respondent type with mistreatment and well-being outcomes, adjusting for individual and program characteristics. Longitudinal survey identifiers linked survey responses for eligible trainees between 2018 and 2019 surveys to further inform nonresponse patterns. Results: In 2019, 6956 (85.6%) of 8129 eligible trainees initiated the survey, with 66.5% Completers, 17.5% Discontinuers, and 16.0% Selective Responders. Items with the highest response rates included dissatisfaction with education and career (93.2%), burnout (86.3%), thoughts of attrition (90.8%), and suicidality (94.4%). Discontinuers and Selective Responders were more often junior residents and racially/ethnically minoritized than Completers. No differences were seen in burnout and suicidality rates between Discontinuers, Selective Responders, and Completers. Non-White or Hispanic residents were more likely to skip questions about racial/ethnic discrimination than non-Hispanic White residents (21.2% vs 15.8%; odds ratio [OR], 1.35; 95% confidence interval [CI], 1.19-1.53), particularly when asked to identify the source. Women were not more likely to omit questions regarding gender/gender identity/sexual orientation discrimination (OR, 0.91; 95% CI, 0.79-1.04) or its sources (OR, 1.02; 95% CI, 0.89-1.16). Both Discontinuers and Selective Responders more frequently reported physical abuse (2.5% vs 1.1%; P = 0.001) and racial discrimination (18.3% vs 13.6%; P < 0.001) on the previous survey (2018) than Completers. Conclusions: Overall response rates are high for this survey. Prevalence estimates of burnout, suicidality, and gender discrimination are likely minimally impacted by nonresponse. Nonresponse to survey items about racial/ethnic discrimination by racially/ethnically minoritized residents likely results in underestimation of this type of mistreatment.
